Cherrypicking is bad -- except when I do it
That seems to be the Warmist idea. The amusing Phil Plait has praised to the skies a long article by Tamino, an inveterate Warmist, which sets out incontrovertible evidence that global warming is real. So I had a look at that article. Tamino says:
"The satellite data for temperature in the troposphere is what senator Ted Cruz likes to use when he claims global warming isn’t happening. But he doesn’t show all of it — just the part after 1997. That way, he can start his graphs with that big fluctuation in 1997-1998, so that fluctuation will look like it’s part of the trend. It isn’t. But Ted Cruz wants you to think it is, so he won’t show you what happened before that — proper context would reveal how shallow his argument is."
So it's bad to choose your starting points for a graph. But Tamino himself does exactly that. His first graph starts from 1880 and his next one starts in 1970. And so it goes. He has many graphs and many different starting points for them. They start wherever he needs them to start to make his case. I won't reproduce anything further from his article but you can log on and see for yourself.
Tamino is very good at lying with statistics. It would be amusing to see him start all his graphs from 1880. In fact, if you look at his graph that does start from 1880, you can clearly see that warming levelled out from around the year 2000. There was a rise last year but that was due to the El Nino weather cycle. So there was some slight warming in C20 but none in the present century. Will it resume? Nobody knows.
